Product feature:
It is characterized by heat shock resistance, low thermal conductivity, no cracking in the whole process of pouring steel, no broken rod.
Plug head brick and water position brick
The brick is located at the throat of the ingot, which is eroded by the vortex of molten steel, and the corrosion is the most severe, so the quality of the brick is maximum.
